LLUMINATED SIGN.

To all whom lit 1muy concern:

ll'armcr; K. WILEY. and lYiLLLm S. Horen, Jr., citizens of the UnitedStates of America, and residents of St. Catherines, in the Province ofOntario and Doniinion of Canada, have invented certain new and usefnlImprovements in Illuminated Signs, of which the following is aspecification.

Our ini ention relates t.) signs in general, and to illuminated signs inparticular.

The objects of the invention Aare to produce a maximum brilliancy, witha minimum number of lamps; to protect'the reflecting surfaces from dirt.and the weather; to eliminate all useless portions of the retlectinsurfaces, for the purpose of reducing bu 'and weight; to eradicateblurring effects i and localized bright' spots, and to provide a durablesign for loi-.g distance vision, aswell as for short range.

Thestatenient of the invention is as follows, it being noted that. thevarious scopes of the invention are attended to in the claimshereinafter annexed.

The organization, underlyingr our conception, ponsists of a plurality ofcent-ral segments of parabolic reilectors placed relatively to eachother so as to form a character,

the arrow Y.

a box whose contour is that of said character,

surrounding said reflectors, a glass plate covering said box, and lampsfor the rellectors.

Figure 1 is a front elevation of'the device.

a portion of a modified reflector, on anen' larged scale. Fig. 4 1s afront elevatloh of a modifiedA construction of the letter Fig. 5, is aside View of that portion of the letter N, at the left of the line W' Z.F1g. 6 is a front elevation of the frame used 1n eferring particularlyto Figs. l and 2,

the structure consists of a. box, shaped like mental parabolicreflectors 3, grouped to form the letter H, and located inside of said'box l, the redecting portion of the reflector being tfnatportion of aparaboloid, which lies between two parallel planes, respeo,

tively on opposite sides of the axis of the Be it known that we, Roi R.lVILErM e respectively located at the foci of the reflecln operation`the light is divided, one portion being reflected by cach reector S, ina beam of light having' approximately a rectangular shaped crosssection, another por` tion being thrown forward by the fiat surface 9,at the back of the lamp, and another portion striking the reflector 5,then the reff ectors 9 and 8,`and finally leaving the device, while.some of the light radiated to the reflector 5, passes through the holesthereof,

and evens up` the. general brilliancy of the character.

Our invention may be modified Without departing from the spirit thereof.Instead of tte more connnon parabolic surface of spoon shape= thesurface 8a maybe that described by a parabolic curve moved parallel to aplane which coincides with the axis of the parabola, and farther andfarther away from said plane, Fig. 3; being anA enlarged side View o aportion of such a parabolic surface, and Fi s. 4, 5 and 6 being di'erentviews o connote parabolic surfaces applied in a modified construction.The said modified construction embodies the l mission of 2class frontsand casings for the reectors.

le will now' describe the modiiications shown in Figs. 4, 5, and (3.vseries of retlectors A., B, C, &c., -are mounted end to end on an Nshaped frame, composedo long and narrow boxes G, which contain theWiring H' for the lamps H. I represents cross braces for making thestructure suitable for shipping and for endurance. J 100 representsbolts and nuts for attaching the letter N tol supports usually on thetops or sides of`buildings.

By this simple construction, it, is easy to provide signs several feetvhigh, and by 105 means of only one lamp in each reflector, i

the sign appears brilliant all over its surface, and at great distancesaway.
